If you're having trouble getting motivated, start taking notes on your training. This will help you maintain perspective on how much progress you've made and what's working and what's not, and it will keep you on track to meet your goals. In your log, record your mileage; your pace; what the weather conditions were; what you ate and drank before, during, and after your run; and how you felt.
